title: Gallates of isoorientin and (2S)-1,2-propanediol glucoside from the leaves of Schoepfia jasminodora.
abstract: From the 1-BuOH-soluble fraction of a MeOH extract of the leaves of Schoepfia jasminodora collected from Okinawa Island, two new galloyl esters and 15 known compounds were isolated. The structures of the new compounds were elucidated by spectroscopic analysis to be isoorientin 4″-O-gallate and (2S)-1,2-propanediol 1-O-β-D: -glucopyranoside 6'-O-gallate. The compounds possessing galloyl or cathechol moieties showed equal radical scavenging activity.
